unfortunately you are absolutely wrong.
americans can take a **** on piece of toast, put a stars and stripes print on it, sprinkle some bacon on it and germans would shortly after import that **** and smear it all over their bodies because they are so ******* in love with american trends.
Its rediculous!
ANY ******* **** americans do, germans have to copy it and sport it 3-5 years later thinking they are the hottest most stylish **** on the planet.
Even if its the most retarded **** ever.

Asia usually did it first, but in a weird way. A little less than half the time, America did it first and Asia just adds to it. This is mostly due to the heavy trade relations between Japan, China, and the U.S. These two areas are the ones that start trends, the rest of the world marginally starts trends, but nothing groundbreaking like console video games (America, it's still America now, but it's about half and half with Asia and some other countries.) , bubble tea (Taiwan) , frozen yogurt (America, expanded by Asians) , Jazz (America) which evolved into Rock and then Metal (America, expanded by Europeans as seen in The British Invasion.), animation (Originally French, but popularized by Disney, which was American, and then became a huge hit in Japan and later throughout Asia in the late 20th century. It's done all over the world now.) . As you can see, the U.S. and Asia are responsible for a lot of trends and the popularization of trends, but Europe still comes up with stuff. Not so much anymore, but they still come up with stuff.
